Description

A hinged joint of raw bamboo

【Technical field】

The utility model relates to a articulated joint, in particular to a articulated joint of raw bamboo.

【Background technique】

In the absence of global timber resources, bamboo has the characteristics of easy reproduction, fast growth, early maturity, and high yield. Moreover, a successful afforestation can be selectively cut down every year for sustainable use without damaging the ecological environment. Bamboo has straight texture, light and elegant color, tough material, and has many advantages of hard broad-leaved wood. It is an ideal material for the production of interior doors, furniture, floors and various components. Pure bamboo home furnishing products are not only practical commodities, but also quite ornamental, which makes people feel comfortable returning to nature, and can also feel the breath of traditional Chinese culture.

However, no relevant reference materials have been seen in the use of protobamboo for building construction. Due to the particularity of the beams and columns used in building construction as load-bearing materials, the original bamboo beam-column connection structure manufactured by the existing technology has fewer forms and poor reliability, and it is difficult to meet the requirements of building construction.

【Content of utility model】

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a hinged joint of raw bamboo.

In order to achieve the above object, the utility model adopts the following technical solutions:

A hinged joint of raw bamboo, comprising a connecting rod of raw bamboo and a steel casting, wherein the steel casting is provided with a hinge point, the inner diameter of the end of the steel casting opposite to the hinge point is greater than or equal to the outer diameter of the connecting rod of the original bamboo, and the connecting rod of the original bamboo is connected to the connecting rod of the original bamboo. A number of bolt holes are provided at corresponding positions in the circumferential direction of one end of the steel casting relative to the hinge point, and one end of the steel casting relative to the hinge point is sleeved on the original bamboo connecting rod, and fixed through corresponding several bolt holes by several bolts.

The utility model is further improved in that two bolt holes are provided at the corresponding position in the circumferential direction of one end of the hinge point of the original bamboo connecting rod and the steel casting, and the central axes of the two bolt holes are vertical in space.

The utility model is further improved in that one end of the steel casting relative to the hinge point is in clearance fit with the original bamboo connecting rod.

The utility model is further improved in that four steel strips with radians are evenly extended from one end of the steel casting relative to the hinge point and are sleeved on the original bamboo connecting rod.

Compared with the prior art, the utility model is an original bamboo hinged joint, which combines the original bamboo connecting rod with the steel casting, and the steel casting is provided with a hinge point, so that the original bamboo can be used as a better In addition, the utility model has the advantages of low energy consumption and low carbon emission due to the use of raw bamboo as a raw material. In addition, the utility model has a simple process and is convenient for popularization and application.

【Description of drawings】

Fig. 1 is the overall structure schematic diagram of a kind of original bamboo articulated joint of the utility model;

Fig. 2 is an exploded view of a hinged joint of raw bamboo of the present invention.

Wherein: 1 is the original bamboo connecting rod, 2 is a steel casting, and 201 is a hinge point.

【Detailed ways】

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Referring to Fig. 1 and Fig. 2, a hinged joint of raw bamboo of the present invention comprises a connecting rod 1 of raw bamboo and a steel casting 2, wherein the steel casting 2 is provided with a hinge point 201, and one end of the steel casting 2 is opposite to the hinge point 201 Four steel belts with radians are evenly stretched out, the inner diameter of the steel casting 2 opposite to the hinge point 201 is greater than or equal to the outer diameter of the original bamboo connecting rod 1, and the circumferential direction of the original bamboo connecting rod 1 and the steel casting 2 relative to the hinge point Two bolt holes are provided at the corresponding positions, and the central axes of the two bolt holes are vertical in space. One end of the steel casting 2 opposite to the hinge point 201 is set on the original bamboo connecting rod 1, and passes through the two corresponding two bolt holes. fixed by a bolt hole.

It should be noted that the end of the steel casting 2 opposite to the hinge point 201 is in clearance fit with the original bamboo connecting rod 1 .

The above content is a further detailed description of the utility model in conjunction with specific preferred embodiments. It cannot be determined that the specific embodiment of the utility model is limited to this. Under the premise of the new concept, some simple deduction or replacement can also be made, which should be regarded as belonging to the utility model and the patent protection scope is determined by the submitted claims.
